WOOD-HOG.

STPECIFIGATION forming part of Letters Patent No. 542,075, dated July 2,1895.

Application filed February 4, 1895*. Serial No. 537,287. (No model.)

T0 all wiz/ont t may concern:

Be it known that I, EDWARD W. BROWN, a citizen of the United States,residing at Bay City, in the county of Bay and State of Michigan, haveinvented certain new and useful Improvements in NVood-I-Iogs, of `whichthe following is a speciication, reference being had therein to theaccompanying drawings.

The invention consists in the construction of asupporting-frame, inwhich a cutting-cylinder is journaled having a hood which incloses thetop of the cutting-cylinder and has formed integral therewith thefeed-spout and also an adjustable bottom having throatplates; further,in the construction of the throat-plate, and, further, in theconstruction, arrangement, and combination of the various parts.

In the drawings, Figure 1 is a vertical cen tral longitudinal sectionthrough a machine embodying my invention. Fig. 2 is adetached`perspective view of the cutter head or cylinder; and Fig. 3 is alongitudinal section through the cylinder, illustrating the manner ofsecuring the cutting-teeth in position.

In the prior state of the art wood-hogs have been manufactured whichembody a casing and a revolving cutter supported therein, the

` casing having a hood hinged at one side and adapted to close the topof the cylinder; but in these constructions the throat-plate has beensupported upon the frame of the machine, and as these throat-plates werenecessarily arranged at or aboutthe middle of the cylinder such supportpresented an obstacle which prevented the ready removal of the cylinderfrom the machine.

By arranging, as I do, the throat-plate upon the feed-spout and formingthe feeding-spout with the hood practically the entire side can beopened by opening the hood, which gives me easy and complete access tothe cutter for repair or removal. My construction also enables me tobuild the throat-plate in such a manner that it may be either attachedor detached quickly, and so that one or more throatplates or bed-plateknives may be employed, and so that the machine having asingle knife ofthis kind may be transferred quickly and with little expense into amachine having a multiple of such knives.

A is the base, preferably rectangular and having on the sides bearingsfor the shaft B, on which is secured the cylindrical cutterhead C. Thishead has apertures D, in front ot which are the recesses or grooves E toprevent clogging of the teeth F with the chips. On the inner face of thecylinder, around the apertures, are the lugs G, and at the ends of thecylinder are the ears H, in line with the lugs, these lugs and earsbeing apertured in line to receive the securing-bolt I,which passesthrough apertures in the stems J of the cutters F, the heads of whichare on the outer face of the cylinder, as plainly shown in Fig. l. Theseteeth or cutters are staggered, and all the teeth combined preferablymake a single clean cut the width of the cylinder, or nearly so.

L is a hood or cover hinged to the rear end of the frame, adapted toinclose the top of the cylinder. This hood at the end opposite the hingeis provided with the inclined spout M, the' lower edges of which restupon the flanges N on lthe base. Within this spout is supported thebed-plate-knife support O, which comprises the side plates P, havingsegmental apertures a for the securingbolts b, and the bed-plates, ofwhich there may be one, as c, or a second one c. By forming the slots ain the parts O the bed-plates may be moved up and dow-n, or in a lateraldirection substantially at right angles tothe length. On each bed-plateis supported the bed-plate knife d, adjustable longitudinally by meansof the screw-bolts e.

By having the feed-spout complete on the hood, when the hood is raisedthe wheel can readily be rolled out for renewals and repair.

By having a detachable bed-plate support inthe spout I can send out amachine with a single bed-plate knife; and if at any time a double knifeis required, can simply detach one plate and insert one with the knives.The space between the knives is lled by a flange f, which preferablyconnects the side plates P.
